Ibice ni indwara zisanzwe zumuhanda munini na asifalt. Amafaranga menshi akoreshwa mugukata igikoma mugihugu buri mwaka. Muri iki gihe, ni ngombwa cyane cyane gufata ingamba zijyanye no kuvura ukurikije indwara zo mu muhanda no kugabanya amafaranga yo kubungabunga.
Kubice, mubisanzwe nta muti usabwa. Niba hari uduce twinshi kuri buri gace, gufunga hejuru birashobora gukorwa kuri bo; kubice bito hamwe nuduce duto, kubera ko bitarigeze byangirika byubatswe, mubisanzwe gusa igifuniko cyo gufunga gikozwe hejuru, cyangwa ibice byacuzwe kandi byuzuyemo kole ya kashe kugirango ushireho ibice.

Gukoresha kole ya kole nimwe muburyo bwubukungu bwo gufata neza umuhanda. Irashobora gufunga neza ibice, gukumira kwaguka kwimihanda kubera amazi yinjira, kandi ikirinda guteza indwara zikomeye, bityo bikadindiza iyangirika ryimikorere yimikoreshereze yumuhanda, bikarinda kugabanuka byihuse byerekana imiterere yumuhanda, no kongera ubuzima bwa serivisi ya umuhanda.
Hariho ubwoko bwinshi bwo kubumba inkono ku isoko, kandi ibikoresho nibikoresho bya tekiniki byakoreshejwe biratandukanye. Inkono yo kubumba yatunganijwe kandi ikorwa na Sinoroader ni ibikoresho bifunga umuhanda byubaka ubushyuhe. Ikozwe muri matrix asfalt, polymer ndende, polymeriseri, inyongeramusaruro nibindi bikoresho binyuze mugutunganya bidasanzwe. Iki gicuruzwa gifite ubwiza buhebuje, ubushyuhe buke bwo guhinduka, ubushyuhe bwumuriro, kurwanya amazi, gushiramo imbaraga no kurwanya gusaza.
