Asphalt Modifiers - Pavement Interactive

Asphalt Modifiers. Some asphalt cements require modification in order to meet specifications. Asphalt cement modification has been practiced for over 50 years but has received added attention in the past decade or so. The added attention can be attributed to the following factors (Roberts et al., 1996 [1] ): Increased demand on HMA pavements.

Asphalt Additives – Pavement Interactive

Additives. Asphalt additives are any of a number of substances that can be added to the asphalt binder to alter the characteristics of the final blend of HMA.. Sasol. Sasol production meets about 30% of South Africa’s transportation fuel needs. There are two major plants in South Africa, one at Sasolburg, which is a natural gas raw feed, (formerly coal) and one at Secunda, which is a coal ...

Asphalt Safety – Pavement Interactive

Asphalt Safety. Asphalt cement, like most other materials, volatilizes (gives off vapor) when heated. At extremely high temperatures (well above those experienced in the manufacture and construction of HMA) asphalt cement can release enough vapor to increase the volatile concentration immediately above the asphalt cement to a point where it ...

Test Research on Optimal Application of BMA Modified

This paper studies the performance changing case of modified asphalt and its mixture with a new asphalt modifier BMA. The performance tests have been done by adding different content of BMA, such as penetration, softening point, ductility of asphalt, and rutting, water damage of asphalt mixture. The study results show that the BMA modifier is an effective asphalt modifier.
