A B. (PCI of 70 or greater) Micro surfacing is a surface treatment designed to extend the life of asphalt pavements in good condition by providing skid resistance, restricting moisture intrusion, protecting the structure from further oxidation and raveling, and restoring a uniform black appearance. It is the most economical choice when leveling ...

Pavement or road-surfacing stones contg. sand, gravel, cement and a filler (e.g. limestone flour) are improved by addition of 5-25 wt. % of a ferromagnetic iron-contg. material (such as iron granules, casting sprinkle and/or an iron ore) having a grain size within the range 0-12 mm. These stones can be laid by an electromagnetic machine on a suitably prepd. sand …

 · Micro-surfacing. Where roads are in a reasonable condition, we may choose to apply a micro-surfacing treatment. Micro-surfacing is a way of extending the life of the road by applying a new top layer which seals out water. It consists of a thin layer of bitumen, fine graded aggregates and a filler which is pre-mixed and applied cold.

Published: 2007. This specification and guidance notes describe the required properties of open graded porous asphalt for use as a surfacing course for road pavements. This mix type is intended to be used as a surfacing where there is a requirement for texture depth, noise reduction and/or splash and spray suppression.

 · Road pavement is that mixture of gravel, aggregate, and asphalt or concrete laid down on a specific route for vehicular and foot traffic. In the past, it only consisted of gravels and stones, but these gradients were later replaced by high-quality materials such as asphalt binder and concrete. Today, pavement design is considered a significant ...

Abstract. Pavement surfaces provide a key route of ingress of rain water into the pavement construction. Thus, permeability of asphaltic materials and the water ingress capacity of cracks in the pavement are very important. A range of equipment exists to determine the permeability of asphaltic mixtures both by in-situ and laboratory testing.
