Relatively thick layers of materials are generally used to maintain pavements subjected to high loadings. However, new asphalt mixes offering a combination of otherwise conflicting properties - high stiffness and flexibility - now make it possible to reduce these thicknesses.

Modulovia® - The time-tested solution

  1. 1. HIGH MODULUS ASPHALTIC CONCRETE MODULOVIA ® The time-tested solution
  2. 2. MODULOVIA® HIGH MODULUS ASPHALTIC CONCRETE Relatively thick layers of materials are generally used to maintain pavements subjected to high loadings. However, new asphalt mixes offering a combination of otherwise conflicting properties - high stiffness and flexibility - now make it possible to reduce these thicknesses. Modulovia®, developed by Eurovia, belongs to this new generation of solutions that combine a wide range of benefits. k EY FIGURES k EY BENEFITS Reduced pavement thickness Conservation of natural resources Production possible with Tempera process ® Between 50 and 90mm of thickness, depending on the formula Over 20 years of technical success Certified under the Road Innovation Charter in 2002
  3. 3. FOR UNRIVALLED PAVEMENT REINFORCEMENT e conomically sound 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 lowtemperature 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.
  4. 4. Spectacular Proven PERFORMANCES 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. Modulovia® with Styrelf® 13/20 has been (under a previous product name) selected by the Direction des Routes as part of the Road Innovation Charter and obtained a certificate in 2002.
