The research of the factors that influence the noise-reducing effect asphalt concrete gradation and shows that the 60mm thick porous asphalt mixtures of the porous of 5% (dense gradation) and 20% (open gradation) porosity have better acoustic absorption function. The two samples of 60mm thick asphalt mixture fit the following formula: ap=0.042Vc - 0.053. The two asphalt mixture samples of 15mm and 10mm maximum granule diameter also have similar frequency and coefficient in acoustic absorption under the condition of similar thickness and porosity. Though it is possible to improve the asphalt mixture's capability of acoustic absorption by increasing its connective porosity, yet the hardness and wearability of the pavement will also be reduced accordingly. Out of this consideration, the paper set the initial porosity as 20%.
The hardness and basicity of basalt and its easy conglutination with asphalt make it the selected material for coarse and fine aggregates (stone chips, sands). To pave the skid-proof wearing layer of open gradation, the best material is modified asphalt, which can solve the problem of semi-rigidity of Shangdong base course, and the problems of thin asphalt layer like water damage, fissure and the rapid attenuation of its skip一proof capability, thus can prolong the longevity of the asphalt pavement. Yet the cost of the modified asphalt is relatively high. Through experiment we find that addition of SBS and MAC modifier would increase the cost by 20% and 18% separately compared with normal asphalt. The major problem confronting highway constructors and domestic manufacturers is to resolve the conflict between the high cost and the good performance of SBS and MAC. In order to improve the loose-proof capability of the porous asphalt, and considering the pollution and harm of mineral fiber-asbestos cement, also the high cost of polymer chemical fiber, the paper adopt loose wood fiber, in accordance with the present experience and application of domestic situation.
