Modulovia® is a high modulus asphaltic concrete made with a special modified binder developed by Eurovia. This exclusive asphalt mix is employed as a surface, binder and base course in pavements subject to unusually high loadings - heavy traffic, severe slopes and surface temperature variations - in both urban and rural areas.

Modulovia® is both strong and flexible. It is rutting resistant and has very good fatigue and crack resistance. As a structural mix, Modulovia® can be used to reduce pavement thickness and thereby conserve natural resources.

… anD HIGHlY FleXIBle

This mix is suitable for both flexible pavement reinforcement, which makes the most of its high modulus and deformation capacity, and structural maintenance of thick or semi-rigid asphalt pavements, in which its stiffness and low-temperature crack resistance are of interest.

The type of binder and mix designs used in Modulovia® make it a very effective asphalt mix:

> high stiffness modulus> excellent fatigue behaviour> very good rutting resistance.

The surface characteristics are identical to those of a semi-coarse asphaltic concrete of the same grading. If a higher macrotexture is required, Modulovia® can be overlaid with an appropriate surface course.

Dense-graded Modulovia® is applied in a 50 to 70mm layer in 0/10 and 60 to 90mm in 0/14 grading. The binder used in its composition is a hard bitumen highly modified with polymers - Styrelf 13-20.

Modulovia® complies with the EN 13108-1 “Bituminous mixtures” standard. It is an HMAC of the highest class covered by the standard, Class 3.

Modulovia® exhibits test results far superior to those obtained with HMACs based on conventional binders. The table below presents the measured mechanical properties of a number of Modulovia® formulas.

The use of hard polymer-modified bitumen in the surface course eliminates the risk of thermal cracking, which can occur under extreme weather conditions when pure bitumen of equivalent grade – 20/30 or 15/25, for example – is employed.

During the thermal stress restrained specimen test (in-house operating method; 10°C temperature reduction), the breaking temperature is – 28°C for Modulovia®, while for a pure 20/30 bitumen it remains – 23°C.
