Iowa Motorcycle Ride Meter, HR-1019, 1980

The Iowa Department of Transportation (Iowa DOT) through the Highway Division is responsible for the design, construction and maintenance of roadways that will provide a high level of serviceability to the motorist. First, the motorist expects to be able to get where he wants to go, but now he also demands a minimum level of comfort. In the construction of new roadways, the public is quick to express dissatisfaction with rough pavements. The Highway Division of the Iowa DOT (formerly Iowa State Highway Commission) has a specification which requires a "smooth-riding surface". For over 40 years, new portland cement concrete (pcc) pavement has been checked with a 10-foot rolling straightedge. The contractor is required to grind, saw or mill off all high spots that deviate more than 1/8" from the 10-foot straight line. Unfortunately, there are instances where a roadway that will meet the above criteria does not provide a "smooth-riding surface". The roadway may have monger undulations (swales) that result in an undesirable ride. The objective of this project was to develop a repeatable, reliable time stable, lightweight test unit to measure the riding quality of pcc pavement at normal highway speed the day after construction.

Correlation Studies BPR Type Roughometer vs. PCE Type Road Meter, MLR-68-2, 1968

The BPR type Roughometer has been used by the Iowa State Highway Commission since 1955 for the evaluation of the relative roughness of the various Iowa road surfaces. Since the commencement of this program, standardized information about the roughness of the various Iowa roads with respect to their type, construction, location and usage has been obtained. The Roughometer has also served to improve the economics and quality of road construction by making the roughness results of various practices available to all who are interested. In 1965, the Portland Cement Association developed a device known as the PCA Road Meter for measuring road roughness. Mounted in a regular passenger car, the Road Meter is a simple electromechanical device of durable construction which can perform consistently with extremely low maintenance. In 1967, the Iowa State Highway Commission's Laboratory constructed a P.C.A. type Road Meter in order to provide an efficient and reliable method for measuring the Present Serviceability Index for the state's highways. Another possibility was that after considerable testing the Road Meter might eventually replace the Roughometer. Some advantages of the Road Meter over the Roughometer are: (1) Road Meter tests are made by the automobile driver and one assistant without the need of traffic protection. The Roughometer has a crew of four men; two operating the roughometer and two driving safety vehicles. (2) The Road Meter is able to do more miles of testing because of its faster testing speed and the fa.ct that it is the only vehicle involved in the testing. (3) Because of the faster testing speed, the Road Meter gives a better indication of how the road actually rides to the average highway traveler. (4) The cost of operating a Road Meter is less than that of a Roughometer because of the fewer number of vehicles and men needed in testing.

Plastic Air Content versus Hardened Air Content by High Pressure Air Meter, MLR-99-03, 2001

Plastic air content is typically tested by the pressure method, ASTM C138. Loss of air content through the paver has been shown to exceed 2 percent at times. Research has shown that early deterioration of pavements in Iowa may be directly or indirectly related to low or inadequate air content. Hardened air content is typically checked using the linear traverse method, ASTM C457. The linear traverse method is very time consuming and could not be used on a production scale. A quick and effective method of testing in place air content is needed. Research has shown a high degree of correlation with the high-pressure method of determining air content of hardened concrete versus plastic air content in laboratory conditions. This research indicated that air contents are more variable when comparing core results to plastic air content, although the overall average for the air content was comparable. Perhaps, the location of the plastic air content test, obtained from construction records, versus location of the cores was not as accurate as needed.
