Sarcee Trail Project

Pre-Rehabilitation Condition:

• Extensive, moderate and high severity centerline and longitudinal cracks in both lanes. Transverse cracks were spaced at 20 m (65 ft) intervals on average and about 20-25mm (0.7-0.9 inches) wide, most of them were sealed. • Intermittent low severity rutting, average rutting was less than 9mm (10.4 inches). • Semi continuous wheel path fatigue cracking of medium to extreme severity, extensive potholes. • Several asphalt patches placed over localized failures observed in the wheel paths. However, the moisture trapped in the subgrade was pumping the water under truck loads, causing the disintegration of patches. New patches were not lasting more than a few weeks, requiring significant maintenance in spring and summer seasons. • Extensive medium and high severity transverse and longitudinal cracks on both lanes. Transverse cracks were closely spaced at 5m (16 ft) intervals. • Semi continuous wheel path fatigue • Negligible rutting. • Negative slope (sloped towards the median) on the median lane was observed in certain areas. • Extensive potholes where longitudinal and transverse crack intercept. cracking of low to medium severity predominantly in the median lane.
