Road network managers, both public and private, today face the same dilemma:

  • budgets for road maintenance are limited and are increasingly used for
    curative maintenance
  • good quality raw materials are becoming scarcer and more expensive, resulting
    in the search for a compromise between performance and cost.

At the project management level, there is an urgent need to find long-lasting and economical techniques to reconcile technical requirements with budgetary requirements on one hand, and sustainable development including user safety and comfort, on the other hand.

With this in mind, Lhoist, your partner for transportation infrastructure and construction management, has developed the Asphacal® range of lime-based products (hydrated lime, quick lime and limestone) to improve the durability of asphalt structures.
