A method of employing a safe and effective flexible plastic curb and gutter. The method of installing a curb along the side of a road having a lower layer prior to laying a top layer of asphalt on the road comprises providing elongated curb strips each having i) a horizontal holding side portion having spaced openings cut therealong; and, ii) a uniformly continuous upright trough portion having a lower edge portion continuously attached to the outer edge of the horizontal side portion. An upper edge portion of the upright trough portion is adapted to extend above the upper layer of asphalt so that water running off the road is channelled along an inner side of the upright trough portion. The horizontal holding side portion of the elongated strip is seated along and parallel to an outside edge portion of the lower layer so when the top layer of asphalt is laid thereon adhesion between the layers through the openings therethrough hold the elongate curb strip in position.

1. A method of installing a curb along side of a road having a lower layer prior to laying a top layer of asphalt on the road comprising the following steps:a) providing elongated curb strips each having i) a generally horizontal lower holding side portion having spaced openings therealong, said lower holding side portion adapted to be seated parallel to the edge of the road on the outer edge portion of the lower layer, and beneath the top layer of asphalt so that the elongated strip is secured in position therebetween by adhesion between the layers through the spaced openings therealong; and, ii) a uniformly continuous and unbroken upright trough portion having a lower edge portion continuously attached to the outer edge of the generally horizontal side portion, and an upper edge portion adapted to extend above the top layer of asphalt so that water running off the road is channelled along an inner side of the upright trough portion parallel to the edge of the road; b) positioning the elongated strips end to end, each along an outer side of the lower layer so that the upright portion of each strip extends upwardly above the outer side of the lower layer; and, c) laying the top layer of asphalt generally above and on the lower layer thereby permanently securing the elongated strips in position by adhesion between the layers through the openings in the generally horizontal holding side portions of the elongated strips; so that water running off the road will be channelled along an inner side portion of the continuous and unbroken upright trough portions of the elongated strips.
