Furthermore, the effects of rutting did not correlate with mixture or aggregate porosity Based on these results, it is evident that an aggregate gradation for a porous asphalt mixture can be optimized depending upon the performance requirements (permeability or strength) based on.

EFFECTS OF DIATOMITE AS FILLER ON THE POROUS ASPHALT

asphalt mixture Ordinary Portland cement also has the potential to be used as additive but there is limited research regarding the use of cement as filler in asphalt mixtures (Huang et al, 2010) Therefore, this study evaluates the effect of using diatomite as filler on the properties of porous asphalt through abrasion loss, resilient modulus and.

Effects of Diatomite Filler on the Performance of Porous

A new method to improve the performance of porous asphalt mixtures by using diatomite as the filler of the mix is introduced in this paper Diatomite is a kind of nonmetallic mineral material Due to its lightweight, high void content, low density and strong sorption.

Resistance to Degradation of Porous Asphalt Mixture Using

Porous asphalt is an open graded mixture predominantly made up of coarse aggregates, which allows water to drain quickly through its porous structure Due to a very high void content, the mix is able to prevent aquaplaning during rainy days (Aman et al, 2014a) However, a high percentage of air void content provided in porous asphalt can cause.

Influence of Different Rubber Modified Binder Variables on

Porous asphalt is a type of pavement in which surface water can permeate down into the subbase below Open graded friction course (OGFC) is a type of porous asphalt often used as a surface course on top of dense graded pavements on high speed roadways Due to an increase in waste tires, rubber modified asphalt has become an increasingly popular material around the world, including the US.
