What is Asphalt EAPA

An asphalt pavement consists of different asphalt layers. In general the asphalt layers are paved on a bound or unbound road base layer. Starting at the road surface, the first layer is called the surface course. The second layer is mostly called the binder course. The lower layers are the

Asphalt f rost protection layer (approx. 34cm) To prevent damage caused by frost, a frost protection layer is often used below the asphalt layers. The unbound gravel, sand or chippings are extremely resistant to heat, water penetration derive quickly and prevent awakenings due to frost in the upper layers of asphalt.

Investigation into causes of in-place rutting in asphalt

20 2-3-  � 83; Inadequate compaction is a major cause for the final rutting depth. Also the aggregate gradation has a major contribution to rutting. The gradation between . 8 and 4.75 mm in sieve size becomes finer for the three layers. The upper and middle layer show an increase in asphalt content, but the lower layer presents a decrease in asphalt content.

Meanwhile, the thickness of the asphalt surface layer specified by Malaysian PWD is divided into two layers, namely, the wearing layer and the binder layer, and the range of each layer is 0.04 to 0.05 m and 0.04 to 0. m, respectively. Taking into account these two layers as the surface layer of asphalt, the range obtained is 0.04 to 0. 4 m.

You want to accomplish a very uniform appli ion of about 0.03 to 0.05 gal/sy of residual asphalt on the layer to be tacked (a paint job, so to speak). Slow-setting emulsions generally have a residual asphalt content of about 2/3. Therefore, an appli ion rate of 0. 0 to 0. 5 gals/sy of the diluted material will give you the 0.03 to 0.05 gals/sy.
