- ABSTRACT Apparatus for forming a series of spaced parallel grooves in the surface of a newly laid pavement slab characterized by engaging the surface of the pavement slab with a molding cylinder having a plurality of eircumferential ribs formed thereon and moving the molding cylinder across the surface of the pavement slab while simultaneously rotating the molding cylinder about its longitudinal axis at a rate slightly greater than a free roll.
- Means are disclosed for preventing damage to the parallel edges of the pavement slab during the grooving process. and means are disclosed for simultaneously spraying water on the surface of the pavement slab and the surface of the molding cylinder during the grooving process.
- the invention relates generally to method and apparatus for treating the surface of concrete. and more specifically. but not by ⁇ vay of limitation. to method and apparatus automatically forming parallel grooves in the urface of a nevvly laid pavement slab 2, Brief Description of the Prior Art It has become desirable in the construction of pavement slabs for highvvays and airport runvvays to provide grooves in the surface of the slab to provide runoff channels for vvater to prevent the tires of automobiles or aircraft from riding on the surface of the water on the pav ement slab thereby causing los ofcontrol of the vehicle. This phenomenon is knovvn an aquaplaning.
- Knovvn examples of the prior art teach various systems for providing grooves in the surface of pavement slabs.
- One method of forming such grooves is to use a rotary savv blade to cut grooves in the surface of a cured pavement slab. This method is extremely slovv and evpensive.
- Another I ⁇ 'IIO ⁇ 'I'I method of achieving this objective is to dravv a sledge. having spaced parallel ribs formed on the bottom side thereof. across the surface of a nevvly laid pavement slab to forln grooves therein.
- Apparatus for practicing thi method has prov ed somevvhat unsatisfactory due to damage done thereby to the surface of the pavement slab.
- the prior art also teaches the use of cylinders having circumferential ribs formed therein which are rolled freely across the surface of a nevvly laid pavement slab to form grooves therein. This method has also proved unsatisfactory since it tends to force a portion of the newly laid pavement along in front of the molding cylinder vvhich also damages the surface of the nevvly laid pavement slab. Yet another knovvn prior art system utilizes the counter rotation of the molding cylinder as the molding cylinder is traversed across the surface of the nevvly laid pavement slab. This latter method. as vvell as the previously mentioned methods, provides less than satisfactory surface finish to the newly laid pavement slab,
- the present invention contemplates a method of forming a series of spaced parallel grooves in the surface of a newly laid pavement slab having substantial parallel edge portions comprising the steps of engaging the surface of the pavement slab with the molding cylinder having a plurality of spaced circumferential ribs formed on the cylindrical surface thereof. pressing the molding cylinder into the surface of the pavement slab to imhed a portion of the ribs in the pavement and to press a portion of the cylindrical surface of the molding cylinder against the surface of the pavement.
- An object of the present invention is to provide an improved method of forming a series ofspaced parallel grooves in the surface of a nevvly laid pavement slab (ill ⁇ vhich ⁇ vill provide a substantially smooth surface ⁇ vith parallel grooves formed therein.
- Another object of the present invention is to provide an improved method of forming a memorized parallel grooves in the surface of a nevvly laid pavement slab vv hich vv ill not damage the surface of the pavement slab.
- Yet another object of the present invention is to pro vide an improved method and apparatus for forming a series of spaced parallel groove in the surface of a nevv Iy laid pavement slab vv hich vv ill neither damage the surface of the pavement slab nor damage the parallel edges of the pavement slab.
- Another object of the present invention is to provide an improved apparatus for forming a eries of spaeed parallel grooves in the surface of a nevvly laid pavement slab vvhich is of simple construction. is reliable in oper ation. and is economical to maintain.
