STEEL REINFORCEMENT OF ASPHALT PAVEMENTS ON AIRFIELDS

STAALARMERING AV ASFALTBELAEGGNINGAR PAA FLYGFAELT: FAELTFOERSOEK OCH ERFARENHETER 1996

Recent inspection of the condition of all military airfield pavements found that total length of cracks and joints is 900 km. Each km costs SEK 100,000 to maintain every 5 years. Apart from maintenance costs, cracks/joints entail indirect costs concerning flight safety. Full width mesh reinforcement of 80,000 sq m runway costs SEK 3m excluding asphalt. Swedish Fortifications Administration has decided to start a campaign to counter cracking. Apart from steel or glass fibre mesh reinforcement, other measures will also be studied. Results of steel mesh reinforcement of a taxiway at one airfield were good. Measurement of wet friction at 95 km/h and 1 mm water film showed a mean of 0.5. Mean of texture measurement by sand patch method was 0.59 mm. At another airfield, steel mesh reinforcement also had satisfactory results. The method is considered satisfactory for crack prevention and also increase bearing capacity. The mesh is specially made and can be laid very efficiently. The only difference in laying the asphalt course is that the paver must not brake since this may cause mesh to bend upwards into the asphalt. Generally, vehicles must drive carefully on mesh. Thickness of asphalt course must be at least 4 cm to ensure sufficient cover.
