, the filial of Ferrovial dedicated to the development
of asphalt products started to produce and supply a new binding agent made with modified bitumen, or HiMA (Highly Modified Asphalt
) towards the end of 2015. This product enhances car and motorbike adherence
on conventional roads and is highly recommended to prevent skidding
Ditecpesa has worked on the design of an asphalt mix for client Max Infraestructuras
, testing the product on the paving of the DR7 racing track located on the Valencia highway near Tarancón, in the province of Cuenca (Spain).
These paving products need to be made with HiMA modified bitumen, and their particle size design must strike a difficult balance between providing adherence and creating excessive friction: adherence will avoid vehicles skidding during a race, but excessive friction will slow them down.
“The technical challenge is not just the binding agent and particle size, but also the physical laying of the road surface, with impossible radiuses for the asphalting machinery involved given the track’s very marked curves and slopes”, says José Javier García Pardenilla, Manager Director at Ditecpesa.
With this new project, Ditecpesa gains further experience in the development, manufacture and laying of this new asphalt mix, consolidating its technological know-how in the field of binding agents and asphalt paving.
