The City of Allen’s street maintenance operations works hard to preserve and maintain the community's investment in municipal roads, alleys and sidewalks. There is a total of 12 full-time staff assigned to maintaining over 300 lane miles of roadway in the City of Allen.
The streets division actively conducts routine, preventive maintenance on the City’s roadways. Preventive maintenance extends the life of the road to keep it looking and riding in like-new condition. The work performed under the preventive maintenance program includes crack sealing and pavement lifting. The purpose is to stop water from entering the roadway, which causes early break up of the road surface. The useful life of roads can be extended if small breaks are fixed before more severe damage occurs. This is the reason why maintenance work is at times done on streets that appear to be in good condition.
The streets division conducts annual street and alley condition assessments and uses this assessment to formulate the pavement maintenance program. This multi-level rating system rates the roadways for ride quality, drainage, and surface & base conditions.
Crack sealing is scheduled when cracks in the roadways expand and become more visible. Filling or sealing pavement cracks to prevent water from entering the base and sub base will extend the pavement life by three to five years. Filling cracks and joints with asphalt materials is a cost effective way to extend the usable life of a road.
Another method of maintaining the roadways, sidewalks and alleys is to repair pavement that has settled.
The City of Allen uses a foam injection to control pavement settlement that occurs under and around roadways, alleys and sidewalks.
Pavement lifting is a non-disruptive, cost-effective, long-lasting solution for correcting settlement on panels connecting sections of concrete or panel misalignment.
