Wearing course versus asphalt: costs and benefits HIM

Jun 26, 2018 Asphalt has a layer thickness of about 10 cm. The layer thickness of a wearing course including the anti-slip aggregate is only 7-10 mm. That has a big impact on the weight. The weight increase using asphalt is high with approximately 250 kg per m2.

Asphalt concrete

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process w

The Effect of Latex on Permanent Deformation of Asphalt

Jan 01, 2017 Thus, the purpose of this experimental study was to investigate the effect of latex in preventing deformation of the asphalt concrete wearing courses (ACWC). Four different latex to asphalt mixtures were investigated, namely 0%, 2%, 4% and 6% latex by weight of asphalt binder respectively. A wet process was used in the mixture blending.

Asphalt Pavement Construction Asphalt Institute

The Asphalt Institute strongly endorses the use of RAP in asphalt mixtures. RAP has a history of positive performance. The specifying agency or owner will set the limit for RAP content. Almost all state highway departments now allow the use of RAP. A few restrict its use in wearing courses; even fewer (one or two) prohibit its use completely.
