Prior to the work, the County will mark the soft areas that require granular fill and shall be identified by stakes with blue flagging indicating the beginning and end of the granular fill segment. Through the course of the project, if the Contractor determines there to be additional areas that require Granular fill, the Owner shall be consulted and the area confirmed prior to adding the Granular fill.
Following scarification of the subgrade, the application of the granular material shall be applied then covered with material recovered from the shoulders, or from imported clay fill. These soft areas shall have an application of 4-40 granular fill material or alternate fill approved by the County Resident, applied approximately 100 mm thick.
The granular fill shall be deposited on the prepared area in a uniform manner and quantity which will produce the required compacted thickness and width designated by the County.

Through the course of the project, if the Contractor determines there to be additional areas that require Clay fill, the Owner shall be consulted and the area confirmed prior to adding any Clay fill.
The application of the clay material shall be following scarification of the subgrade and recovery of material from the shoulders as part of the shoulder pull. The clay fill shall be deposited to the prepared area in a uniform manner and quantity which will produce the required compacted
thickness, width, and elevation as directed by the County. All material placed in embankments shall be spread and bladed smooth in successive layers, not to exceed 0.15 m in depth when compacted and to the full width of the cross-section. Contrary to 2.3.4.7.5.2 “Test Methods” of Specification 2.3 Grading, the test method used for the testing of the subgrade for compaction will be a tandem water truck, supplied by the Contractor, loaded to the maximum legal capacity. Acceptance or rejection of the compaction will be at the discretion of the Owner.
Camrose County reserves the right to withhold sufficient funds from the payments to complete the work necessary to obtain compaction to ensure a maximum deflection of 15 mm. Deflection in excess of 15 mm will require a reworking of the subgrade to achieve the desired density and stiffness.
The County has the right to reject any unsuitable material.
5.13.1 Clay Fill - (Contractor Supply)

The Contractor shall construct the roadway to the design cross section such that the finished surface has a 8 m top (road width), 3% crossfall from the centre (crown) and 3:1 side slopes. The existing subgrade shall be scarified to depth of 150 mm and incorporate excavated material from the shoulders in lifts not greater than 150 mm, mixed and pulverized with a disc or soil reclaimer and blended to form a homogenous mix of material. All rock in excess of 75 mm diameter shall be removed from the graded and re-compacted soils for each lift of applied material.
Work is to progress in a sequential fashion and be limited to 800 m – 1600 m segments. The side slopes are to be groomed and trimmed to a neat and consistent fashion equivalent to H3:V1 ratio.
Contrary to 2.3.4.7.5.2 “Test Methods” of Specification 2.3 Grading, the test method used for the testing of the subgrade for compaction will be a tandem water truck, supplied by the Contractor, loaded to the maximum legal capacity. Acceptance or rejection of the compaction will be at the discretion of the Owner.
Camrose County reserves the right to withhold sufficient funds from the payments to complete the work necessary to obtain compaction to ensure a maximum deflection of 15 mm. Deflection in excess of 15 mm will require a reworking of the subgrade to achieve the desired density and stiffness.
In the event of a dispute of the roll test between the Contractor and the Owner, tests will be performed by an independent Geo-Technical company to verify the results. If the independent tests confirm the results indicated by Owner, the Contractor will be responsible for any and all costs incurred to perform the tests. If the tests show that the Contractor has achieved the required compaction as specified in the Contract, the Owner will be responsible for costs incurred for the independent testing.

5.14.2 Approach Treatment
The shoulder pull road is primary, and the design cross section and crown must be maintained and constructed through each residential and farm approach as per the Drawings. Once the shoulder pull is completed to its desired shape, then the approaches shall be transitioned to the road edge.

Measurement of the Shoulder Pull will be made according to the stationed distance of the primary roads being impacted, and as identified in the Unit Rate Table.
Payment for Shoulder Pull will be made at the unit price bid per linear metre for “Shoulder Pull”.
