DETAIL SPECIFICATIONS.

THE REQUIREMENT.

It is required that there be constructed in accordance with these specifications a brick pavement on

This pavement to extend from curb to curb as same may be hereafter determined.

EXCAVATION.

Shall be included in the price of bid on per square yard. The roadway shall be excavated to the necessary depth below the established grade of the finished roadway, to provide for the thickness of pavement, and thoroughly rolled with a 5 ton roller, until the surface of the sub-grade is soild, and approximately parallel to the proposed surface of the contemplated pavement. Soft and springy places not affording a firm foundation shall be dug out and refilled with food sound earth, [strikethrough] cinders, gravel, concrete, slag or stone, as the engineer may direct, such extra excavation to be paid for at actual reasonable cost of labor and materials, plus 15 per cent.

The contractor shall dispose of all excavated material as directed by the engineer. Where the haul upon this material does not exceed 3000 feet no extra compensation shall be allowed.

For distances greater than 3000 an overhaul allowance of one cent per cubic yard for each additional one hundred feet shall be made.

In the prosecution of the work the contractor will be held responsible for all damages done to pipes and conduits.

MARGINAL CURB.

Whenever the brick pavement is joined to macadam, gravel or other surface not affording proper support to the edge of the brick pavement, a marginal curb shall be used. This curb shall be made of a hard and durable stone or concrete, at least six inches wide and fourteen inches deep if of stone. This curb shall be dressed on top and five inches down on the face next to the brick. It must be set to accurately fit the curviture of the cross section of the street, and on six inchs of

-2-

concrete and backed up with same to within six inches of top of curb. The concrete for this shall be of same proportion and materials as that used for the concrete foundation for pavement.

CONCRETE FOUNDATION.

Upon the prepared sub-base shall be placed and throughly tamped a five inch layer of Portland Cement concrete.

This concrete shall be composed of one (1) part Portland Cement and nine (9) parts first class pit gravel containing a proper proportion of clean sharp shand and no gravel larger than two (2) inch

Separation of sane and gravel and recombination, will not be insisted upon unless tests made on materials coming to the work show an objectional disproportional of either element.

A barrel of Portland Cement will be considered as four cubic feet. A standard bag will be considered as one cubic foot.

The approved pit gravel shall be measured in bottomless boxes 6 feet long, four one-half feet wide and one foot high accurately struck off. three standard bags of cement being used to each measure of gravel.

The work of measuring and mixing shall be done on a platform of two inch planks of proper size, tight joints and resonaably level. After the proper amount of cement shall have been evenly spread upon the gravel the bottomless box shall be removed and the mass throughly mixed by turning and re-turning with shovels.

The concrete shall be mixed at least four times. Two times wet and two times dry.

After the mass has been well mixed dry, water in sufficient quantities shall be gradually added while the mass is being throughly mixed. Care must be taken in the amount of water used in making the concrete so that it is neither lacking in water to give it proper setting nor too wet.

After the concrete has been properly made it shall be placed by barrows or direct shovelling in a single layer five inches thick and well tamped into place. .

Upon this foundation no birck shall be laid for a period of laest two days and the contractor shall protect and barricade

-3-

this base from all traffic and disturbance of any kind except when specific orders to the contrary are given by the engineer.

SANDCESSHION

Upon the prepared concrete base shall be placed a two inch layer of screened river or dead. This sand shall be clean and free from foreign or loamy matter. It shall be spread by means of a template conforming to the required cross section of the street.

BRICK.

The brick shall be hauled and neatly piled near the work and carried from the pile by hand. In no case shall throwing or dumping the bricks be allowed.

The bricks shall be first class paving bricks, thoroughly vitrified and showing at least one fairly straight face. The bricks shall be of uniform size and color, free from cracks, with but slight lamination and shall stand the tests recommended by the National Paving Brick Makers Association.

BRICK LAYING.

The brick shall be laid on edge and at right angles to the line of the curbing and the line or course of the bricks shall be kept straight or within a maximum variation of 2 inches.

If greater than that as many courses as necessary shall be taken up and relaid until the defect in alignment is removed.

No parts of brick shall be allowed in the pavement except the beginning or ending of courses or other closures.

The bricks shall be laid with broken joints and with each brick struck against the side and end of the bricks already in position.

The brick shall be closely inspected before laying and also after laying and after tamping and all soft bricks or badly spolled or ill-shapen or discolored bricks shall be removed and replaced with perfect ones.

ROLLING.

After the bricks in the pavement are inspected and the surface swept clean of spolls they must be well rolled with a five ton roller in the following manner: The bricks next the curb shall be
