4. HOW TO CALCULATE THE WEIGHT OF ASPHALT Now a day’s asphalt paving is a very popular material as paving. The mostly driveway paving companies also recommend asphalt for paving work as parking lots, residential driveway, or commercial road, etc. In calculating the weight of asphalt, necessary is the volume and specific gravity. It can be derived by calculating the volume from the construction area and thickness of the asphalt pavement and multiplying the specific gravity of the asphalt used for pavement. Here, I will explain the basic knowledge which is the prerequisite for weight calculation and the attention abnormal to asphalt. 

5.  ABOUT SPECIFIC GRAVITY • “Specific gravity” is a word indicating how heavy an object is with respect to the same volume of water. Since the specific gravity of the reference water is 1 and the weight per square meter is clear as 1 ton, weight can be calculated concisely by multiplying the volume by the specific gravity of the object. • Specific gravity is determined by the “density” of the object. Density is a term expressing the weight per volume of an object, the higher the density, the higher the specific gravity. • Specific gravity becomes very important to calculate the weight of asphalt.

6.  THE CALCULATION METHOD FOR FINDING WEIGHT FROM VOLUME • When calculating the weight of asphalt by calculation, you can use a method of multiplying the volume by specific gravity. • Volume is obtained by multiplying the construction area by the thickness of the pavement, but usually, the asphalt is pressed slightly because it is treated with a road roller etc. after spreading. • This is called “rolling reduction”, and it is necessary to calculate it taking into account the volume of stepped down. Since the volume decreasing by treading is considered to be approximately 8%, 1.08 is multiplied by the calculation formula as the rolling reduction. • Based on the above, the weight calculation of asphalt is expressed as follows. • Area (m 2) × thickness (m) × specific gravity × rolling reduction (1.08) = weight (t)

7.  POINTS TO NOTE WHEN CALCULATING • In general, asphalt used for paving is called “dense particle size asphalt mixture”. • Although the specific gravity is set to 2.35, the specific gravity determined by the manufacturing company may differ depending on the product asphalt actually used for construction. • Let’s ask the asphalt shipping contractor in advance to ask the gravity to confirm. • The specific gravity also varies depending on the type of asphalt used as described below. The calculation can be done smoothly by checking what kind of asphalt to use at the time of construction.

8.  THE DENSITY OF ASPHALT MIXTURE • The so-called “asphalt” used for paving is officially called an asphalt mixture and is classified according to density. • Each type of asphalt mixture has different strength and weight. • Differentiation of the asphalt mixture is determined by the size and density (= particle size) of the blended particles, and there are “dense grain asphalt mixture”, “fine grain asphalt mixture” and “open grain asphalt mixture” in order of strength. • Since the strength and properties of asphalt required for paving change, change the type to use according to the required strength.

9. THE TYPE CHANGES ACCORDING TO THE RATIO OF ASPHALT MIXTURE  The materials that make up the asphalt mixture are as follows. • “Coarse aggregate”:- A relatively large gravel or crushed stone, with more than 85% left when sieving the eye size to 5 mm filter. • “Fine aggregate”:- 85% falls through a 5 mm sieve, relatively small gravel, and crushed stone. • “Filler”:- A fine powder of mineral which further crushed gravel and crushed stone into crushed powder. It has the role of filling the gap between the aggregate. • “Asphalt”:- Adhesive that summarizes the above aggregate and filler as a connection and completes it as an asphalt mixture. The residue of Petroleum to separate gasoline and heavy oil and purify. If you use cement instead of asphalt for concrete, it becomes concrete.

10.  DENSE PARTICLE SIZE ASPHALT MIXTURE: • Asphalt pavement which is most often seen in everyday life, it is often used for road paving. It is characterized by large grains mixed, there is an advantage that it is inexpensive and can be constructed in a short period of time. • It is an important characteristic that it is hard to deform, it is resistant to wear, and the anti-slip effect is high.

11.  FINE PARTICLE SIZE ASPHALT MIXTURE: • It is a pave that mixed a lot of smaller grains than those of dense grain size. Because the particles are small and the gaps characterized by high water resistance and strong resistance to cracking. • Open grain size Asphalt mixture: • It is a pavement with small grains distributed at low density. Even if the surface compares the above two, it is characterized by being very rough, it is said that it is hard to make a puddle to suck water well. • Moreover, in order to prevent moisture from staying on the surface, it also has the characteristic that the road surface is hard to slip. are small, they are

12. THE DIFFERENCE IN SPECIFIC GRAVITY AND PERFORMANCE OF ASPHALT MIXTURE:  • The specific gravity and performance of each general asphalt mixture, the scenes to be used are summarized below. • Dense particle size Asphalt mixture • Specific gravity: 2.35 • Performance: The most popular asphalt for paving. Strong, slip resistant, construction is cheap. • Mainly used places: Road with many passengers including national highways. A part with a sharp gradient. • Fine particle size asphalt mixture • Specific gravity: 2.30 • Performance: Water resistant to cracking hard. On the other hand, it has difficulty to deform. • Mainly used places: Where heavy trucks such as heavy-duty trucks frequently operate and parking lots.

13.  OPEN GRAIN SIZE ASPHALT MIXTURE • Specific gravity: 1.94 • Performance: Water drainage is good, the road surface is easy to dry, so it is difficult to slip. On the other hand, wear resistance is lower to the above. • Mainly used places: Locations where road surfaces are likely to get wet, such as places that are prone to flooding and snowy countries.

14.  UNIT WEIGHT OF ASPHALT • If you know the specific gravity, you can calculate the weight per volume by weight. Below is the weight per cubic meter of each asphalt mixture. • About 2.5 tons of dense grain asphalt mixture • Fine particle size asphalt mixture About 2.4 tons • Open grain size asphalt mixture About 2.0 tons • The above unit weight is multiplied by the number which is regarded as general gravity to the last.

15. PROCEDURES FOR USING ASPHALT ON OUTSIDE CONSTRUCTION  • The external structure is a term other than the construction of the building that refers to the structure inside the buildings, the whole of the exterior. In addition it seems that driveway paving contractors suggest asphalt, and also there are many people who want to pave their parking lots with asphalt material as well. • This discussion may help you if you want to pave your driveway or parking lot yourself or want to hair an asphalt paving company. Concrete and asphalt are generally used for the exterior pavement, but here I will explain the step by step construction when using asphalt

16. BASIC KNOWLEDGE OF ASPHALT CONSTRUCTION  • I will introduce the basic properties of asphalt, the structure when laying on the ground, and the place where asphalt is used as pavement material. • Basic properties of asphalt • When we so-called asphalt for paving is the official name "asphalt mixture" and is manufactured by blending asphalt and some other materials. The materials are roughly classified in descending order as follows. • Coarse aggregate • It is relatively large gravel and crushed stone. This is about 85% of the large grain that remained through a 5 mm eye filter. Pavement materials mixed with coarse aggregate are rough on the surface, enhancing durability and anti-slip effect. • Tine aggregate • It falls on a 5 mm sieve and refers to relatively small gravel or crushed stone. The surface of the paved road which contains a lot of fine aggregates is finely fine and becomes strong against water and cracks.

17.  WHERE ASPHALT IS OFTEN USED • Generally speaking, asphalt is often seen in roads such as general roads and highways. Asphalt is widely used for road pavement from its excellent road characteristics. • However, even outside the road, repairs are easy, construction costs are cheap, and functionalities such as drainage are high so it may be used for parking lots and housing exteriors. In addition, asphalt is also used as water resistant the material on the roofs.

18.  STEP 1 DRILLING THE UNDERGROUND • In order to build the road floor and the bedrock which becomes the foundation of the road, we first dig in the construction area. Depending on the strength of the ground to be constructed, we will drill the roadbed as much as necessary, dig your driveway soil about 12 cm for a pedestrian and about 25 to 30 cm for the driveway or more according to the use of the driveway. We will reinforce the ground here if the ground is weak. • After excavation, tread the exposed soil with a roller etc. If you need a brick fence or a block fence at the scene at a parking lot or the like, it is installed at this stage.

19. STEP 2 ROADBED ADJUSTMENT/CRUSH PILING  • Lay down crushed stones in the drill holes and form the roadbed. Large gravel is used for the lower roadbed, and small gravel stone is used for the upper roadbed. • Also, decide the height and slope of the roadbed so that rainwater accumulated on the surface of the asphalt flows smoothly to the side grooves. Depending on the shape of the parking lot (extended parking lot etc), it may be necessary to have many slopes.

20. STEP 3 MAKE A ROLLING PRESSURE ON THE ROAD  • To maintain the crushed stone density high, we will roll the roadbed. Put pressure on the crushed stone further with a road roller etc. • Tighten firmly until it reaches the specified density. If rolling pressure runs short, ground subsidence may occur, so it is a very important process.

21. STEP 4 LAY OUT THE ASPHALT COMPOSITE MATERIAL  • We will spread the asphalt mixture forming the surface layer and the base layer. The asphalt softens by heating and solidifies when it cools down, so it becomes a spreading operation while keeping warm if necessary. • Considering that it will settle after completion of the construction, carry out a work called "remaining bulk" to bulge the finished surface of asphalt beforehand. • After the overgrowth is complete, make it so that the road surface becomes flat.

22.  STEP 5 ROLLING THE ASPHALT PAVEMENT • Since asphalt just laid is mixed with air, it is soft and fluffy, so firmly pressurize it with a roller or vibrator to remove air and tread it. • Temperature management becomes very important also during rolling. To finish cleanly it is necessary that the high temperature is maintained, and if it cools down during work it will cause distortion and cracking. • After sufficiently treading down, wait for the asphalt to cool down and be completed.
