Evaluation of Retroreflectometers for the Alabama Department of Transportation
This project performed field-testing and analysis of two pavement marking retroreflectometers: the Laserlux and the LTL2000. The Laserlux is a vehicle-mounted device that takes readings at driving speed and produces computerized output. The LTL2000 is a hand-held device that also provides computerized output. The Federal Highway Administration (FHWA) may soon establish standards for pavement marking retroreflectivity, so the Alabama Department of Transportation (ALDOT) wished to establish which of the two devices would be most useful in complying with future standards. The cost analysis of the two retroreflectometers clearly indicated that the Laserlux is the more cost effective retroreflectometer when measuring the approximately 11,000-centerline miles of the ALDOT system for an analysis period of eight years. The cost to test pavement markings for those circumstances is approximately $5/mile of marking per year for the Laserlux and approximately $35/mile of marking per year for the LTL2000. Only one Laserlux and one crew would be required to perform the testing. Eight LTL2000s and eight crews would be required to perform the same task.
