   Abstract : Application of the proper dust suppressant to a gravel road ensures road safety and riding comfort as well as creating a cleaner and healthier environment for residents in buildings adjacent to the road. It also reduces the need and cost for vehicle repair, road maintenance activities, and aggregate supplementation. READ MORE

5. 3. Implementation and evaluation of an HMA fracture mechanics based design module

   Author : David Gullberg; Björn Birgisson; Robert Lundström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : A thickness design module for flexible pavements, based on the HMA fracture mechanics framework, has been developed in order to design against premature failure caused by cracking. The HMA fracture mechanics based design module has been evaluated by designing typical Swedish pavements under typical Swedish climate and loading conditions and comparing the results with a reference design framework.
