Patent number: 6161429Abstract: Apparatus for measuring two parallel spaced surface profiles is disclosed. The apparatus disclosed has dual laterally spaced beams linked to a transport device shown as a trailer that is towable by a motor vehicle. Each beam has a profiling wheel that measures road surface deviations and transmits the resulting measurements to a recording device. The beams are foldable and stowable on the trailer for transport of the apparatus between measuring sites.Type: GrantFiled: October 13, 1998Date of Patent: December 19, 2000Assignee: Paveset America, LLCInventors: Frederick J. Marvel, Colin T. Fleming, Zbigniew Rybak

Patent number: 6119353Abstract: Equipment for non-contact measurement of the deflection of a road (2) comprises a self-propelled vehicle with a load (7) which influences at least one wheel (4), the speed of which is measured in the direction of travel. The equipment further comprises a laser device (8) from which at least one electromagnetic beam (9) is directed towards the rodway in the vicinity of the vehicle, and the Doppler frequency change in the reflection (9) is detected. An electronic circuit (10) continuously registers the results of the measurements and herewith the deflection at normal traveling speed.Type: GrantFiled: September 19, 1997Date of Patent: September 19, 2000Assignee: Greenwood Engineering ApSInventor: Leif Gr.o slashed.nskov

Patent number: 5878502Abstract: An apparatus for comparing compliance of a grade to a predetermined slope includes a block and a level. The block has at least one notch positioned at a distance from a first end of the block such that when the method of this invention is practiced, a level indicator will indicate whether a grade on which the apparatus is resting matches a predetermined grade. A method of this invention includes the steps of inserting an arm of predetermined length into the notch and placing the joined block and arm on a grade. A level is placed at the arm to thereby compare compliance of the grade to a predetermine slope.Type: GrantFiled: July 18, 1997Date of Patent: March 9, 1999Inventor: Harold B. Donahue, Jr.

Patent number: 5829149Abstract: A profilometer having a beam placement system which includes a beam pivotally connected to a front and a rear foot member. The foot members are spaced along the length of the beam and are arranged to be positioned on a section of pavement. The beam placement system also includes a system for repositioning the front and rear foot members so that, upon forward movement of the profilometer along the pavement whose profile is to be measured, the rear foot member is positioned on the section of pavement previously occupied by the front foot member. The beam placement system additionally includes an apparatus for measuring the slope of the beam between the front and rear foot members.Type: GrantFiled: July 1, 1996Date of Patent: November 3, 1998Inventor: Graham Roland Tyson

Patent number: 5799403Abstract: This invention is a method for remotely obtaining roadway crown point elevation and horizontal location based on projecting a horizontal laser beam configured vertically in either a continuous or discrete manner across the roadway surface at a predetermined elevation substantially coincident with the crown point of the roadway. The highest elevation of the roadway partially occludes the vertically configured laser beam. The lowest elevation of the laser beam which contacts an array of vertically configured laser receivers positioned on the opposite side of the roadway is by necessity the highest elevation of the roadway crown. By using an optical detector at a known vertical offset from the laser beam emitter, the angle and hence the distance can be determined to the furthest laser impact with the roadway. This distance information can be combined with the known line between the laser emitter and laser receivers to resolve the horizontal coordinates of that point.Type: GrantFiled: December 20, 1996Date of Patent: September 1, 1998Inventor: Paul T. Schrum
