More advantages

More advantages with the Compactasphalt® method:

	Improved laying quality & higher durability by: Creating a thicker asphalt layer during laying and therefore an obviously significant extension of the period of time available for final compaction (t~d1,8 ) [1] and the possibility to optimise the degree of compaction, and positively influence the deformation resistance. t= time, d= layer thickness By increasing the layer thickness from 4 cm to 12 cm, the available time for compaction is increased 7 times!

	Reducing the influence of bad weather on the compaction properties of thin wearing courses by using the asphalt binder’s residual heat.
	High and homogenous density through the complete layer depth (wearing course and binder course)	Read more >>
	Excellent interlocking of the courses (Cut power 37KN) [2] Due to its optimum bonding it will better withstand high vertical forces. This is main criteria for the long service life of the asphalt pavement.	Read more >>
	Reducing the appearance of ruts and cracks as it is possible to take up higher vertical and horizontal forces due to optimum degrees of compaction and high layer adhesion (bonding and tight interlocking).
	Better durability can be expected due to a feasible high deformation resistance and good interlocking of the layer, together with optimum air void content.
	With this technology it is possible to extend the planned lifetime of the top layer, to be close to the lifetime of the binder course.
	Economic optimisation of the wearing course’s surface properties with regard to skid resistance, brightness and also the reduction of the course thickness.
	Cost reduction Due to a 50% thickness reduction of the expensive wearing course No bitumen emulsion is needed between the binder and wearing course Significant reduction of paving times due to the simultaneous laying of both courses
