01. TECHNICAL OVERVIEW & ENGINEERING CHARACTERISTICS
Asphalt mixtures produced in accordance with SR EN 13108-1 and Romanian road standard AND 605-2016. Classified into base course (AB22.4 / AB31.5), binder course (BAD22.4), and wearing course (BA16 / MAS16 - Stone Mastic Asphalt). Designed with polymer-modified bitumen (PMB) to prevent rutting under heavy truck traffic in summer (+60°C pavement temperature) and low-temperature thermal cracking in winter (-25°C).
02. CONSTITUENTS & MANUFACTURING SPECIFICATION
- ▸Crushed hard quarry aggregates (basalt, andesite, granite) compliant with SR EN 13043
- ▸Limestone rock filler (<0.063mm)
- ▸Paving grade road bitumen 50/70 or Polymer-Modified Bitumen (PMB 45/80-65 per SR EN 14023)
- ▸Hot-batch production in asphalt mixing plants at 160°C - 180°C
✓ ADVANTAGES & STRENGTHS
- •Smooth, jointless riding surface delivering low tire-pavement rolling noise and high skid resistance
- •Rapid traffic opening immediately after compaction and cooling to ambient temperature
- •100% recyclable into Reclaimed Asphalt Pavement (RAP) for new asphalt production
- •Easily repairable and resurfaced through asphalt cold milling (frezare)
⚠ LIMITATIONS & RISK FACTORS
- •Susceptible to plastic deformation and rutting under static heavy wheel loads if bitumen grade is too soft
- •Vulnerable to fuel and chemical solvent spills that dissolve the bituminous binder matrix
- •Demands strictly controlled weather conditions during paving (no rain, ambient temp ≥ +10°C)
